5,3,12,0,7,11,4,3,8.

Answer 1

Answer:

Step-by-step explanation:

0,3,3,4,5,7,8,11,12

Median: 5

Answer 2

Step-by-step explanation:

Solution :

Arranging the given data in ascending order,

we get,

0, 3, 3, 4, 5, 7, 8, 11, 12.

Total number of observations = n = 9, which is odd.

Therefore :

$median = \frac{n + 1}{2} \: th \: observation$

$\: \: \: \: \: = \frac{9 + 1}{2} \: th \: observation$

$\: \: \: \: \: = \frac{10}{2} \: th \: observation \:$

$\: \: \: \: \: = 5 \: th \: observation$

Hence :

The median is 5.
